IMPROVEMENT IN WATER-WHEEL GOVERNORS.

Specification forming part of Letters Patent No. 156,720, dated November 10, 1874; application tiled September 12, 1874.

CASE B.

To all whom it may concern:

Be it known that I, ALFRED WooDwoRTE, of Cambridge, in the county of Washington and State of New York, have invented a new and valuable Improvement in Water-Wheel Governors; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures ot' reference marked thereon.

Figures 1 of the drawings are representations ot' vertical sectional views ot' my waterwheel governor. Fig. 2 is a transverse vertif cal sectional view of the same.

lhis invention relates to certain novel improvenients on the water wheel governor marked GaseA, and bearing even date with the tiling of this.

The improvements consist mainly in a vibrating pawl-carrier having upon its upper end anti-friction wheels, in combination with actuating mechanism, as will be hereinafter more fully described and claimed.

In the annexedV drawings l have omitted to show the connection of the shaft A with the gate-stein, as this may be done by means of bevel-wheels, or by any other suitable means. l have also omitted to show the stop-motion andthe friction-clamp described and illustrated in my application forLe-tters Patent marked Case A,77 and above referred to.

The shaft A has its end bearings in a suitable frame, B, and on this shaft is keyed a ratchet-wheel, C, the teeth of which are so shaped as will allow pawls a a to turn it either toward the right or left. The pawls a a are loaded, so that they will be held down to their work by their own gravity, and these' pawls are pivoted to two arms, b b, of a bifurcated pawlcarrier, D, which is pivoted to a rod, E, beneath the shaft A, and constructed with a large opening through it, which will allow it to vibrate freely, and also allow shaft A to pass through it. The upper ends of the arms b b of pawl-carrier D bear anti-friction rollers c c, having concave peripheries, be-

tween which rollers is an eccentric, d, which is fixed on the lower end of a short shaft, on which a bevel-wheel, G, is keyed. This wheel engages with a bevel-pinion, G1, on the shaft of a belt-wheel, G2, which receives motion from the mechanism driven by the water-wh eel. J J designate two guards, which are separated from each other by a short space, j, and which are formed on a hub, J1, that is free to vibrate on the shaft A. The hub and its guards are vibrated by the rise and descent of the governor-balls, to which they are connected by means of a rod, K, passing up through the shaft of wheel G. On the opposite side of shaft A to the point where rod K is attached to the hub J1, an arm, J2, is formed on this hub, and to this arm a weight, w, is adjustably applied for balancing the balls ofthe centrifugal governor.

When the guards J J are in the position shown in Fig. l, pins p p on pawls a a will lie upon these guards, and the pawls will be held free from the ratchet-wheel. When the governor-balls rise 011e of the guards J will be moved from `beneath the pin p ot' pawl a, and allow this pawl to engage with the ratchet-wheel G and turn this wheel so as to diminish the tlow of water to the water-wheel.

lf the governor-balls descend below a given point, the pawl a will be caused to engage with the wheel C and turn this wheel so as to open the gate and allow an increase of the flow of water to the water-wheel.

What l claim as new, and desire to secure by Letters Patent, is-

The combination, with the bifurcated vibrating pawl-carrier D, having anti-friction pulleywheels c c upon its upper extremities, of the eccentric d, bevel-wheel G, actuating-wheel G2, and rod E, as and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
